Identification The Comb-footed Platform Spider has a striking patchwork colour pattern, but is best recognised by its moderately large, distinctive web with a leaf detritus retreat. Habitat The Comb-footed Platform Spider is common in bushland and gardens in eastern Australia. Distribution https://australianmuseum.net.au/learn/animals/spiders/comb-footed-platform-spider/ 2/4 6/24/2019 Comb-footed Platform Spider - The Australian Museum + − Feeding and diet When insects fly into the 'knockdown' network of threads of the Comb-footed Platform Spider's retreat, they fall through onto a silk sheet where they are seized by the spider. Other behaviours and adaptations The Comb-footed Platform Spider is not as specialised a retreat builder as the leaf-curling orb weavers; however a curled leaf may be used, or some leaf detritus may be loosely silked together. The retreat is placed in the centre of a network of threads spun above a horizontal, close-meshed silk sheet. These webs are usually built among understorey shrubs and low trees and are often seen in overgrown gardens. Breeding behaviours The egg sacs are placed inside the Comb-footed Platform Spiders' silk retreat. https://australianmuseum.net.au/learn/animals/spiders/comb-footed-platform-spider/ 3/4 6/24/2019 Comb-footed Platform Spider - The Australian Museum Predators The complex webs of the Comb-footed Platform Spider harbour a range of other animals, from small moth larvae that scavenge along the silk lines to spiders that find prey in the outer parts of the web. Some of these are small prey stealers of the genus Argyrodes. However, they include one species that is a specialist predator on A. mundula. Argyrodes incursus is a small, jet black spider with a single red spot on its abdomen. Somehow, the smaller spider kills the larger A. mundula and eats it, finally making its own egg sac within the dead host's retreat.

Cryptachaea gigantipes has been recorded from natural habitats in south-eastern Australia, but is also commonly encountered around houses and other built structures, there and in the North Island of New Zealand. The earliest New Zealand records are from the year 2000 and it would appear that the species has been accidentally introduced due to its synanthropic tendencies. The idea of a recent and limited initial introduction is supported by cytochrome c oxidase subunit 1 (COI) sequences, which are extremely homogeneous from New Zealand specimens compared to those from Australia.

Molecular Insights Into the Phylogenetic Structure of the Spider
MolecularBlackwell Publishing Ltd insights into the phylogenetic structure of the spider genus Theridion (Araneae, Theridiidae) and the origin of the Hawaiian Theridion-like fauna MIQUEL A.

The Hawaiian happy face spider (Theridion grallator Simon, 1900), named for a remarkable abdominal colour pattern resembling a smiling face, has served as a model organism for under- standing the generation of genetic diversity. Theridion grallator is one of 11 endemic Hawaiian species of the genus reported to date. Asserting the origin of island endemics informs on the evolutionary context of diversification, and how diversity has arisen on the islands. Studies on the genus Theridion in Hawaii, as elsewhere, have long been hampered by its large size (> 600 species) and poor definition. Here we report results of phylogenetic analyses based on DNA sequences of five genes conducted on five diverse species of Hawaiian Theridion, along with the most intensive sampling of Theridiinae analysed to date. Results indicate that the Hawai- ian Islands were colonised by two independent Theridiinae lineages, one of which originated in the Americas. Both lineages have undergone local diversification in the archipelago and have convergently evolved similar bizarre morphs. Our findings confirm para- or polyphyletic status of the largest Theridiinae genera: Theridion, Achaearanea and Chrysso.

C. P. 04510. Del. Coyoacán, Ciudad de México, México. E-mail: [email protected] 2Corresponding author Abstract Spider community inventories have relatively well-established standardized collecting protocols. Such protocols set rules for the orderly acquisition of samples to estimate community parameters and to establish comparisons between areas. These methods have been tested worldwide, providing useful data for inventory planning and optimal sampling allocation efforts. The taxonomic counterpart of biodiversity inventories has received considerably less attention. Species lists and their relative abundances are the only link between the community parameters resulting from a biotic inventory and the biology of the species that live there. However, this connection is lost or speculative at best for species only partially identified (e. g., to genus but not to species). This link is particularly important for diverse tropical regions were many taxa are undescribed or little known such as spiders. One approach to this problem has been the development of biodiversity inventory websites that document the morphology of the species with digital images organized as standard views.

A Summary List of Fossil Spiders
A summary list of fossil spiders compiled by Jason A. Dunlop (Berlin), David Penney (Manchester) & Denise Jekel (Berlin) Suggested citation: Dunlop, J. A., Penney, D. & Jekel, D. 2010. A summary list of fossil spiders. In Platnick, N. I. (ed.) The world spider catalog, version 10.5. American Museum of Natural History, online at http://research.amnh.org/entomology/spiders/catalog/index.html Last udated: 10.12.2009 INTRODUCTION Fossil spiders have not been fully cataloged since Bonnet’s Bibliographia Araneorum and are not included in the current Catalog. Since Bonnet’s time there has been considerable progress in our understanding of the spider fossil record and numerous new taxa have been described. As part of a larger project to catalog the diversity of fossil arachnids and their relatives, our aim here is to offer a summary list of the known fossil spiders in their current systematic position; as a first step towards the eventual goal of combining fossil and Recent data within a single arachnological resource. To integrate our data as smoothly as possible with standards used for living spiders, our list follows the names and sequence of families adopted in the Catalog. For this reason some of the family groupings proposed in Wunderlich’s (2004, 2008) monographs of amber and copal spiders are not reflected here, and we encourage the reader to consult these studies for details and alternative opinions. Extinct families have been inserted in the position which we hope best reflects their probable affinities. Genus and species names were compiled from established lists and cross-referenced against the primary literature.

Population Structure in the Spider Achaearanea Tepidariorum (Araneae, Theridri- Dae)
Valerio, C . E. 1977 . Population structure in the spider Achaearanea tepidariorum (Araneae, Theridri- dae) . J. Arachnol . 3 :185-190 . POPULATION STRUCTURE IN THE SPIDER ACHAEARANEA TEPIDARIORUM (ARANEAE, THERIDIIDAE) 1 Carlos E. Valerio Escuela de Biologia Universidad de Costa Rica ABSTRAC T Two distinct types of population structure are present in the spider Achaearanea tepidariorum , each with totally different dynamics and behavior. The floating population or dispersion stage is composed entirely of second instar spiderlings , representing about 99 per cent of the total produced by the species . This population is characterized by a very diverse genetic composition and a high mortality . Several different strategies are observed in spiders in general to reduce mortality in the second instar . The established population is composed of individuals with snaring webs and sedentary habits, an d begins as an immature population after the invasion of an available habitat by the second instar . During this phase, its numbers increase first at the maximum intrinsic rate until the maximum habitat capacity has been reached . In a mature population more than 65 per cent of the biomass is contrib- uted by the adult individuals. INTRODUCTION Although spiders are among the most diversified groups of animals and many specie s are locally very abundant, a review of the literature shows little work done on thei r population biology (Turnbull, 1973) . Two distinct types of population structures are present in many spider species, eac h with different characteristics regarding dynamics and behavior : the floating population and the established population . The characteristic aeronautic behavior (ballooning) is the means of dispersion in mos t spider species.

COSMOPOLITAN AND PANTROPICAL SPECIES OF THERIDIID SPIDERS (Araneae: Theridiidae) By Herbert W. Levi MUSEUM OF COMPARATIVE ZOOLOGY, HARVARD UNIVERSITY Abstract: As a result of study of American theridiid spiders and examination of col lections from other parts of the world 16 species are believed cosmopolitan or Pantropi cal. The 16 species are briefly redescribed with their diagnostic features and genitalia illustrated. A large number of theridiid spiders are cosmopolitan or Pantropical. Although these spe cies were described and illustrated in my revisions of American theridiid spiders, it seems desirable to gather the information together. Not only did I not recognize at the time I described them (often under an American name) that many of the species may be wide spread, but the need to combine the information has also been demonstrated by the discov ery of some species redescribed under new names. The synonymies and descriptions given in the original papers are not included; only the main diagnostic features will be repeated. Several of the commonest species will be pictured in color in a forthcoming book (Levi & Levi 1968) illustrating the features of spider families.

There are tales describing how they lay eggs in human skin, frequent toilet seats in airports, and crawl into your mouth when you are sleeping. Misinformation about spiders in the popular media and on the World Wide Web is rampant, leading to distorted perceptions and negative feelings about spiders. Despite these negative feelings, however, spiders offer intrigue and mystery and can be used to effectively engage even arachnophobic individuals.
